“…The measured discharges of the Yangon and Pathein distributaries are significantly higher and the Bogale is significantly lower than those reported in Brichierei‐Colombi (1983) and Chen (2020). These differences may be due in part to improvements in sampling techniques and differences between remote sensing or modeling and in situ observations.…”

“…This study focuses on the western Pathein, central Bogale, and eastern Yangon distributaries, which represent the full range of distributary discharge conditions. A recent review suggested that the Pathein and Yangon distributaries each carry <10% of the total Ayeyarwady River water discharge and that the Bogale carries up to 19% (Chen et al, 2020), however these values will be challenged here.…”

“…sediment source, climate, and vegetation), allowing us to examine the interplay between deltaic sediment retention and the orientation of the coastline with respect to the tides and monsoon winds. For this comparison it is important to divide the Ayeyarwady Delta into eastern and western regions ( Figure 10), which have different sediment-transport processes and morphologies, as discussed above and in previous studies (Chen et al, 2020). The eastern region includes the Yangon distributary, the western region includes the Pathein distributary, and the Bogale distributary falls near the boundary between regions.…”

Predicting the future stability of vulnerable and valuable deltas requires accurate constraints on sediment retention and export at the river-ocean interface. However, sediment discharge for most rivers is measured above the influence of tides, even though the lower, tide-influenced reach of a river can retain 40%-70% of the total sediment load (Goodbred & Kuehl, 1998; Milliman et al., 1985; Nittrouer et al., 1995). Previous in situ studies of tidal-to-estuarine sediment dynamics have revealed multiple pathways and mechanisms for sediment retention along the tidally influenced reach of a river. Starting in the fresh, tidal river, sediment export tends to dominate within channels, while regular overbank flows deposit sediment on floodplain surfaces (

The Mekong River (MR) is recognized the 12th biggest rivers in the world. The Mekong watershed is the biggest one in Southeast Asia (795,000 km2), is densely populated (70 million people), is considered as the most productive one in Southeast Asia and is economically essential to the region. However, nowadays, the Lower Mekong River (LMR) and its delta are facing several emerging and critical anthropogenic stressors (dams construction, climate change, water poor quality, delta sinking). This review attempts to: (i) present the Mekong regional characteristics (geography, topological settings, climatic conditions, hydrology, demographic features and the anthropogenic activities), (ii) present the different factors that endanger the LMR, including the dam’s impacts, the climate change, the delta subsidence, and the degradation of the water quality, (iii) make comparison with different big rivers around the world and (iv) promote future decisions in order to minimize the negative impacts and seek for a trajectory that assures well-being and sustainability. International consultation and cooperation leading to sustainable management is now of a pivotal importance to try to avoid the deterioration of the LMR and its delta.

The evolution of the Wulan Delta began after the construction of the Wulan River Canal in 1892. It alters the shoreline erosion and accretion that affect the land dynamics of the coastal area. This study aims to analyze the spatio-temporal evolution of the Wulan Delta, including the shoreline and its dynamics, as well as the geomorphological processes that affect it. The shoreline change was extracted digitally from Landsat satellite images and divided into four periods, i.e.
